CTICasesRadiation-Induced Tracheal Stenosis
Imaging findings
CT chest shows severe, fixed narrowing (stenosis) of the trachea and right mainstem bronchus, occurring at the site of a prior lymphoma mass that had undergone radiation therapy. The stenosis has remained stable over two years.
Key takeaways
Radiation therapy to the mediastinum (such as for lymphoma) can cause delayed, chronic airway complications. Radiation-induced tracheobronchial stenosis is caused by ischemic necrosis and subsequent fibrotic scarring of the airway wall, presenting as chronic, fixed narrowing that can cause severe dyspnea.
